There is only one standard prescription for Kariva dosing. This prescription oral contraceptive comes in the form of a tablet that must be taken every day (at the same time each day). If you miss a Kariva dose, you may have to use a backup method of contraception, as missing doses increases your risk of pregnancy. Make sure you know exactly what to do if you miss any pills.
Kariva Dosing: An IntroductionKariva® (desogestrel/ethinyl estradiol) is a prescription oral contraceptive and is a generic version of Mircette®. There is only one standard dose of Kariva. As always, do not adjust your Kariva dose unless your healthcare provider specifically instructs you to do so.
Kariva Dosing for Birth ControlStarting at the beginning of the pack, take one tablet at the same time each day. Each pack will last for four weeks (28 days). After you finish one pack, immediately start a new one. Do not let any days pass between packs (this may take a little planning, as you will need a new pack on hand). The first 21 tablets contain the active ingredients. The next two tablets do not contain any active ingredients, and the last five tablets just contain ethinyl estradiol (no desogestrel). During this last week, your body gets a little break from the hormones, allowing you to have a period.
When you take Kariva for the first time, you can start on either the first day of your period or on the first Sunday after your period starts. If you start Kariva on the first day of your period (a "day 1 start"), you do not need any backup contraception. If you choose a Sunday start, you need to use a backup method of contraception (such as condoms) for the first week. If the first day of your period happens to fall on a Sunday, treat this as a day 1 start (no backup method of contraception needed).
